Which description compares the vertical asymptote(s) of function a and function b correctly?

function a: f(x)= 1/ x+4

function b

both functions have a vertical asymptote at x=−4 .

function a has a vertical asymptote at x = 1.
function b has a vertical asymptote at x = 3.

function a has a vertical asymptote at x = 4.
function b has a vertical asymptote at x = 2.

function a has a vertical asymptote at x=−4x=−4 .
function b has a vertical asymptote at x = 2.

I just took the test, the correct answer is ...

“Function A has a vertical asymptote at x = -4.

Function B has a vertical asymptote at x = 2.”

required rate of return = 0.166 = 16.6%

step-by-step explanation:

under the capital asset pricing model (capm), the required or expected rate of return for a particular security or asset is given using the formula:

required rate of return = risk-free rate + beta*(market risk premium)

we are given that;

risk-free rate = 4% = 0.04

beta = 1.4

market risk premium = 9% = 0.09

we simply plug these values into the above formula;

required rate of return = 0.04 + 1.4*(0.09)

required rate of return = 0.04 + 0.126

required rate of return = 0.166 = 16.6%
